Boolean matrix in mex file

Hello everyone,

I'm trying to read a logical matrix in a mex file with matlab. The way I usally do for reading matrices in matlab is:

double *var = mxGetPr(prhs[0]);

If the variable in matlab is logic, I get weird results in C++, but if I try to initialize var as boolean:

bool *var = mxGetPr(prhs[0]);

I get:

error C2440: 'initializing' : cannot convert from 'double *' to 'bool *'

The only solution I've found, for the moment, is passing the logical matrix as double to the mex routine, but I'd prefer reading the boolean matrix instead.

How can I do that?

Alessandro.

Hi Alessandro,

use mxGetLogicals instead of mxGetPr ...

Thank you, I didn't know about that one.
